One face AB of a prism of prism angle 45° is silvered. An incident ray on face AC retraces its initial path after striking AB. Find the range of refractive index of the prism for which it is possible at least for some angle of incidence:

If one face of a prism angle 30^(@) "and" mu= sqrt2 is silvered , the incident ray retraces its initial path. What is the angle of incidence?

One of the refracting surfaces of a prism of angle of 30^(@) is silvered. A ray of light incident at an angle of 60^(@) retraces its path. The refractive index of the material of prism is

A ray of light is incident on the face AB of a glass prism ABC having vertex anlge A equal to 30^(@) . The face AC is silvered and a ray of light incident on the face AB retraces its path. If the refractive index of the material of prism is sqrt(3) find the angle of incidence on the face AB.

A ray of monochromatic light is incident on one refracting face of a prism of angle 75^(@) . It passes thorugh the prism and is incident on the other face at the critical angle. If the refractive index of the material of the prism is sqrt(2) , the angle of incidence on the first face of the prism is

The angle of minimum deviation for an incident ligt ray on an equillateral prism is equal to its refracting angle. The refractive index of its material is

A ray of light incident normally on an isosceles right angled prism travels as shown in the figure. The least value of the refractive index of the prism must be

A prism ABC of angle 30^(@) has its face AC silvered. A ray of light incident at an angle of 45^(@) at the face AB retraces its path after refraction at face AB and reflection at face AC . The refractive index of the material of the prism is

A ray of monochromatic light is incident on the refracting face of a prism (angle 75^(@)0 . It passes through the prism and is incident on the other face at the critical angle. If the refractive index of the prism is sqrt(2) , then the angle of incidence on the first of the prism is

ABC is right angled prism kept in air. A ray (1) is incident on the face AB along the normal. Another ray (2) is incident on the face AB such that it emerges normally form the face AC. Then The minimum value of refractive index of the material of the prism for which the ray 1undergoes TIR on the face AC is

A ray of light is incident at 60^(@) on one face of a prism of angle 30^(@) and the emergent ray makes 30^(@) with the incident ray. The refractive index of the prism is
